LADLE FOR MOLTEN METAL.

To all whom it may concern.-

Be it known that I, GUSTAV A. I-IAssEL, of McKeesport, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Ladles for Molten Metal, of which the followingis a specification.

The object of my invention is to provide a new and improved ladle formolten metal and to this end my invention consists of a ladle, havingthe novel features of construction and the combination of parts all asfully herein.- after described and claimed.

In the accompanying drawing, which illustrates an application of myinvention Figure 1 is a part front elevational view and a part sectionalview of a ladle constructed in accordance with my invention; Fig. 2 apart side elevational view and a part sectional view; and Fig. 3 adetailed sectional view taken on line 33 of Fig. 2.

Referring to the drawing the ladle 1, as illustrated and as preferred,is made of an integral cast-steel structure embodying trunnions 2,radial ribs 3 and annular strengthening ribs 4. In addition to theseparts I provide around the top of the ladle an inwardly extending flange5. The function of the flange 5 is to protect the brick-work or othersuitable lining 6. The ladle is also formed with a bottom pouringopening 7 formed in the bottom of the ladle. An annular bead 8 surroundsthe opening 7. The ladle is also formed with a top pouring lip 9 .andwith lugs or eyes 10 near the bottom of the ladle.

1 1 designates a bail having end portions 12 engaging with therespective trunnions 2. The bail is engaged by forked latches 13,located at the upper end of the ladle and secured thereto by bolts 14which latter are adapted to be passed through apertured lugs 15preferably formed integral with the ladle.

*The ladle illustrated is designed to contain a large quantity of moltenmetal and I desire to call particular attention to the fact that theladle proper comprising all the parts above mentioned with the exceptionof the bail, the latches 13 and the bolts 14 are made in one integralstructure and not built up of numerous parts as, so far as I am aware,has heretofore been the practice. The advantages in providing a ladleformed of a single cast-steel structure over a built up ladle will bereadily appreciated by those skilled in the art.

Specification of Letters Patent.

Application filed June 27, 1907.

Patented June 23, 1908.

Serial No. 381,010.

In the ladle illustrated I have shown strengthening bands 16 and 17,-the sidebands 16 extending downwardly from the trunnions and bolted tothe bottom-band 17 The bottom-band 17 is riveted to the bottom of theladle. These bands, however, do not constitute an essential feature ofmy invention and may be entirely dispensed with.

Another characteristic and important feature of the present invention isthe stopperrod actuating and adjusting mechanism.

18 designates a stopper-rod which is moved vertically within the ladleby an operating lever 19. b As illustrated, lever 19 is con nected witha slide 20 by means of arm 21. Slide 20 is provided with a groove 22 andis adapted to slide in a guide-way 23 which latter is secured to theexterior of the ladle as clearly shown by the drawing. The upper end ofthe slide 20 is provided with an outwardly projecting plate-member 24having a curved contacting or bearing-member 25. In addition to themember 25 said plate 24 is provided with bolt receiving-openings 26.

27 is a lock-nut extending into the groove 22 and is designed to lockthe slide in the desired position in its guide-way 23.

Located directly opposite the member 24 of the slide I employ a member28 compris ing a body-portion 29 formed with a tapering opening 30extending through said body and adapted to receive a tapering rod 31.Rod 31 is connected with the stopper-rod by means of a rod 32. Member 28is provided with a plate-member 33 corresponding to the plate 24 and isformed with a recess or socket 34 adapted to receive the roundedbearingmember 25. Plate 33 is also provided with bolt holes 35 which areadapted to receive bolts 36. Bolts 36 extend through the holes 35 ofplate 33 and through the holes of plate 24 as clearly shown by Fig. 3.Rod 31 is formed with key-ways 37 adapted to receive a key 38.

By means of the adjusting mechanism just described the stopper-rod maybe moved laterally within the ladle to cause thestopper to register withthe pouring-hole in the bottom of the ladle. This is accomplished afterthe stopper-rod is lowered and locked by simply turning the nuts 39 onthe adjusting-bolts 36. The means above described for adjusting thestopper rod are of such a character that the rod will be held firmly inany position to which it may be adjusted, and the clamping bolts forjoining the two adjusting members serve to perform merely the functionof holding such parts together, the rod itself or its connecting rod 31being independently held and supported in the member 28 by means of akey-way and key.

What I claim is:

1. A ladle for molten metal having an integral cast steel body formedwith integral trunnions and having integral ribs extending radially fromthe trunnions to the body, whereby the strain on the trunnions isresisted in all directions.

,2. In combination with a ladle for molten metal having a pouringopening in its bottom, of a stopper rod, means for laterally adjustingthe rod relatively to the pouring opening comprising a member carried bythe ladle, a supporting member having a ball and socket connection withthe ladle member and clamping bolts on either side of said ball andsocket connection and a connecting member between the ball and socketdevice and the stopper rod.

3. The combination with a ladle for molten metal having a pouringopening in its bottom, of a stopper rod, means for laterally adjustingthe rod comprising a slide mounted on the exterior of the ladle andprovided with a rounded bearing member, a socket member adapted toreceive the rounded member, adjustable clamping bolts on either side ofthe members and joinin the same, whereby the socket member is heldfirmly in any adjusted position, said socket member having a bearing fora rod and means connecting said rod with the stopper rod.

4. The combinationwith a ladle for molten metal having a pouring openingin its bottom, of a stopper rod, a rod supporting member having means toengage and hold the rod from rotation and against vertical movement, arounded member mounted on the ladle and adapted to enter a socket insaid supporting member and adjustable clamping bolts independent of therod-holding means for fixing said supporting member in adjustedposition. i

In testimony whereof I ailix my in presence of two witnesses.
